Patent BR-8802177-A (BR)
Inventor: PUETZ HEINRICH
IPC: F16C33/14
Filed: 1988-05-04
Abstract: A method for producing porous bearing shells with a compacted surface for gas-static bearings from sintered hollow blanks includes heating a blank with an inside diameter smaller than a rated diameter of a bearing and slipping the blank in the heated state onto a mandrel having an outside diameter equal to the rated diameter of the bearing. Subsequently the blank is cooled to the operating temperature of the bearing. The blank is reheated and the blank is finally pulled off the mandrel.

Abstract: Polymerization of a monomer charge containing at least one norbornene-type monomer, a ring-opening methathesis catalyst and cocatalyst, an optional halometal activator, and wherein said cocatalyst is selected from alkoxyalkylaluminum, aryloxyalkylaluminum, alkoxyalkylaluminum halide, and aryloxyalkylaluminum halide which are prepared by reacting an alkylaluminum or alkylaluminum halide with an alcohol combination of a first alcohol selected from tertiary alcohols, hindered primary alcohols, hindered secondary alcohols, and mixtures thereof, with a second alcohol selected from unhindered primary alcohols, unhindered secondary alcohols, and mixtures thereof. The use of these branched alcohol combinations results in a longer pot life exceeding about one half hour and a lower mold temperature of 50 to 100 DEG C. This invention is also directed to the composition which includes at least one monomer, an activator which must be used when the cocatalyst is devoid of a halide, and the cocatalyst.

Abstract: This invention relates to a process for preparing polyethylene wax having a narrow molecular weight distribution in a gas phase polymerization reactor. The invention particularly relates to the process of polymerizing ethylene in the presence of a supported metallocene-alumoxane catalyst and hydrogen. The catalyst may be derived from the addition of silica gel containing about 6 to about 20 percent by weight adsorbed water to a trialkylaluminum solution. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dried to free flowing powder. A trimethylaluminum pretreated metallocene may be employed when the trialkylaluminum is selected from the group consisting of triethylaluminum, tripropylaluminum, tri-n-butyl-aluminum, tri-isobutylaluminum, tri(2-methylpentyl)aluminum, trihexylaluminum, tri-n-octylaluminum and tri-n-decylaluminum.

Abstract: A manually powered fastening tool which stores and instantly releases the energy of a spring such that it may force a staple type fastener into an object by an impact blow. In the present invention the squeeze handle is hinged near the end of the tool body opposite the end from which the staples exit. The user grips the tool near the staple exit end and pushes the squeeze handle toward the intended staple impact point. This novel arrangement causes the user to force the staple into the receiving object with the same hand that pushes the squeeze handle toward the tool body, while the prior art typically requires use of a second hand to hold the tool firmly upon the staple impact point. Improving from the prior art, the present design ensures that the staple exit end of the tool body will not lift away from the receiving object. The energy storage spring and handle engagement linkage are located remotely from the plunger in the present design. This allows the user to fully grip the tool near the staple exit end of the tool body. The motion of installing a staple with this novel staple gun is therefore similar to the intuitive motion used with a common desk top stapler.

Abstract: cDNA sequences are disclosed which are expressed specifically in the anther of a plant. Genomic DNA sequences corresponding to the cDNA clones are obtained using the cDNA clones as hybridization probes. Recombinant, or chimeric, DNA sequences are constructed in which the promoter sequence from anther-specific genomic clones are operatively linked to a DNA sequence coding for a desired polypeptide. Transgenic plants are made in which the chimeric DNA sequences are expressed in the anther of the transgenic plant. In a preferred embodiment, the coding DNA sequence expresses a polypeptide which will disrupt formation of viable pollen, resulting in a male-sterile plant. <IMAGE>

Abstract: A flameless combustor eliminates the flamme as a radiant heat source, which results in a more even temperature distribution throughout the length of the burner. Flameless combustion is accomplished by preheating the fuel and the combustion air to a temperature above the autoignition temperature of the mixture. The present invention lowers the autoignition temperature by placing a catalytic surface within the desired combustion chamber. Temperatures are maintained above the catalyzed autoignition temperature but less than the noncatalyzed autoignition temperatures for noncatalyzed reaction. Thus, the amount and location of reaction can be controlled by varying the amount and distribution of catalyst within the burner. Removing heat from the combustion chamber in amounts that correspond to the oxidation of fuel within different segments of the combustion chamber can result in low temperatures and relatively even distribution of heat from the burner.
